The operating principle of complex modulation fuze using pseudorandom code phase modulation and linear frequency modulation is simply introduced. 简单介绍了伪码调相与线性调频复合调制引信的工作原理。
To solve the problem of tracking for direct sequence spread spectrum signals where data is non-coherent with code, a new method of tracking is presented. 摘要针对数据位和伪码周期非相参时直接序列扩频信号的跟踪问题，提出了一种新的跟踪方法。
